What exactly does he mean by discussing the forbidden?

Hmmm... good question. Because Shabbos is so holy, maybe it means we shouldn't discuss avodah zarah. I'll have to ask my Rav.

OK,The Talmud (Avodah Zarah 7a) holds we cannot say to a friend whom he wishes to hire to work for him, "shall we see whether you will join me in the evening( i.e. after the sabbath)?

It is forbidden to hire workers on the Sabbath ( even for work to be done after the Sabbath(Shalchan Aruch, Orach Chaim 307:2) due to the injunction stated in Isaiah 58:13 from "seeking your own interests" i.e. pursuing your business affairs ( Rashi to Shabbos 150a)
